First introduce the following notations:
P=yx^2z^2\\Q=x^2yz^2\\R=x^2y^2z\\\text{Then compute the partial derivative like this:}\\R_y=2x^2yz\\Q_z=2x^2yz\\P_z=2yx^2z\\R_x=2xy^2z\\Q_x=2xyz^2\\P_y=x^2z^2\\\text{Then evaluate each of the following:}\\R_y-Q_z=2x^2yz-2x^2yz=0\\P_z-R_x=2yx^2z-2xy^2z=2xyx(x-y)\\Q_x-R_y=2xyz^2-x^2z^2=z^2x(2y-x)\\\text{Our answer will be then:}\\Curl(f)=(2xyx(x-y))j+(z^2x(2y-x))k

Answer:

9C=5(F-32)

Step-by-step explanation:

The equation which can convert the temperature from degree Celsius into degree Fahrenheit is given as under

9C=5(F-32)

We can solve it further for F as

9C=5F-5 \times 32

9C=5F-160

9C+160=5F

Dividing both sides by 5 we get

\frac{9C}{5}+32=F

F=\frac{9C}{5}+32

Now substituting values of C in this equation will give us the corresponding values of F

Ex : C=1

F=\frac{ 9\times 1}{5}+32

F=\frac{ 9+160}{5}

F=\frac{ 169}{5}

Hence 1 degree Celsius is \frac{ 169}{5} degree Fahrenheit

Answer:

The cost of 16 oz of granola should be $16.16

Step-by-step explanation:

Given that,

The cost of 3 oz of granola is $3.03

We need to find the cost of 16 oz of granola..

As 3 oz = $3.03

1 oz = (3.03/3) = $1.01

The cost of 16 oz will be :

16 oz = 16×1.01

= $16.16

Hence, the cost of 16 oz of granola should be $16.16.

Natalka [10]

Answer:

Total number of milkshakes sold on Monday = 300

Number of milkshakes without whipped cream = 90

Step-by-step explanation:

Given:

Adrienne adds whipped cream to 210 milk shakes which is 70% of the total milk shakes sold.

To find the total milkshakes sold.

Solution:

Let the total number of milkshakes sold on Monday be = x

Percentage of milkshakes with whipped cream added to them = 70%

Number of milk shakes with added whipped cream can be given as:

⇒ 70\% \textrm{ of the total number of milkshakes}

⇒ 70\% x

⇒ \frac{70}{100}x  [Representing percent in fraction form]

⇒ 0.7x  [evaluating in decimals]

We know that the number of milkshakes with whipped cream added to them = 210.

So, we have:

0.7x=210

Solving for x

Dividing both sides by  0.7

\frac{0.7x}{0.7}=\frac{210}{0.7}

∴ x=300

Thus, total number of milkshakes sold on Monday = 300

Number of milkshakes without whipped cream = 300-210= 90
